If you're a college student I suspect that you don't have a lot of money ... If so, building it is the better solution. It doesn't seem too complicated (my armor is on the way). Is there a reason not to build it ? It's part of the pride of having it !
I bought an AP armor, and I took one already trimmed to ease the building. It's a middle-of-the-road solution, since the trimming is very a intimidating part of the process for the newcomers. Once the trimming is done, it's just a question of assembling all the parts with snaps, rivets and velctro. A good way to understand how it works is to meet with fellow Stormtroopers and inspect their armor closely. They will happily answer all of your questions.
Good luck with your project !
